tooltip role doesn't do anything for domains

[Sam Halliday]

Dear all,

I only realised this one after a big refactoring but it would appear that the 'tooltip' role doesn't do anything for domains. i.e. you can't manually set the tooltip for the x axis values (changing the FormattedValue will change the axis which isn't what I want). e.g. http://jsfiddle.net/UqcjT/1/

On a side note, I find the roles to be very confusing - introducing a new role can mess up the column indexing of an entire codebase. I can see that roles permit continual extension which would otherwise clog up the base API, but It seems to me that a cleaner API would have two types of getters/setters. The base get/setValue would affect 'data' and 'domain' roles and get/setRole(role, ...) would be able to change the other roles associated to a (row, column). (This might result in the deprecation of get/setFormattedValue) Any chance of such a change in future APIs?

e.g. for one cell

data.setValue(1, 2, 5.0);

data.setRole(1, 2, 'type', 'data'); // e.g. to switch between data and domain

data.setRole(1, 2, 'formatted', "Five");

data.setRole(1, 2, 'tooltip', "5 lovely bananas");

data.setRole(1, 2, 'upper', 6.0);

data.setRole(1, 2, 'lower', 4.5);

data.setRole(1, 2, 'certainty', false);
